我市常年种植小麦170万亩,其中旱地小麦132万亩,占麦播面积的78%。旱地小麦生产的好坏,直接影响着夏粮生产。旱地小麦生产的主要限制因素是干旱缺水。因此,实现旱地小麦高产,必须围绕提高自然降水利用率这个中心环节,落实以下四项关键措施。一、深耕改土,以土蓄水深耕能加厚耕作层、促进根系发育、增强吸收水分、养分的能力。据有关资料表明,在深耕条件下,根系主要分布在0～50厘米土层内,其中0～20厘米土层内的根量
The city grows 1.7 million mu of perennial wheat, of which 132 million mu of dry land wheat, accounting for 78% of the sowing area. Dry wheat production is good or bad, a direct impact on summer grain production. The main limiting factor for dryland wheat production is drought and water scarcity. Therefore, to achieve high yield wheat in drylands, we must focus on the central task of enhancing the utilization rate of natural precipitation and implement the following four key measures. First, deep plowing and soil improvement, soil plowing and deep plowing can thicken the tillage layer, promote root development and enhance the ability to absorb water and nutrients. According to the data shows that under deep plowing conditions, the roots are mainly distributed in 0 to 50 cm soil layer, of which 0 to 20 cm soil layer
